Poll, called to define three most important inventions, made representatives of the fine half of mankind, started on March 8 on the RuNet and came to the end on September 27.
The first place in the list was occupied with a diaper. This invention in the forties made the last century the present furore among young mums. Used in the early 1920-ties rubber toddlers almost did not solve a pollution problem, and kids had intertrigo from them. But all was changed by the American inventor and young mum Marion Donovan.
Tired of necessity constantly to change diapers and to wash toddlers of her small daughter, and together with them and all her clothes, Marion found a tremendous decision.
She took a curtain for a bathroom and sat at the sewing machine. Through a pair of hours there appeared a water-proof cover for diapers – the first prototype of modern diapers.
First attempts of Donovan to patent and sell her invention did not turn around success; however in 1951 she all the same managed to take out her first patent.
In total 20 patents were given for the woman. Almost her inventions intended for simplification of life of women. But diapers, certainly, became the most popular and revolutionary creation of the scientist.
The second place was given to automobile “yard keepers”.
Long to potter with car, as a rule, hobby of men. However, fine ladies also took a hand in manufacture of cars.
In 1902 inventor Mary Anderson went in a tram in the rainy weather: there was rain with snow and a strong wind. The woman paid attention that the driver should open constantly a shutter of the window and to wipe glass to see the road. Thus, the wind and rain got into salon, delivering inconvenience and to the driver, and passengers.
After a year Mary presented to the patent department of the USA the invention and now a screen wiper – an integral part of any car.
The third place in the list was occupied with the dishwasher. To wash mountains of dirty dishware in the kitchen – destiny of each woman. But thanks to Josephine Cochrane it became easier to millions housewives to cope with this not palatable duty.
In 1887 the first dishwasher designed by Josephine Cochrane was presented to Chicago – the daughter of engineers, the granddaughter of the inventor of the first American steamship of John Fitch.
Creation of this remarkable invention by Cochrane induced negligence of the servant. Once again having seen, as during washing the servants broke expensive porcelain plate from family service, Cochrane had in a fit of temper exclaimed: «If nobody is going to invent the dishwasher, I will be engaged in it!».
She also kept a word, having constructed the mechanised car for washing of dishware with a manual drive. The debut of Cochrane’s device took place at the world’s fair in 1893. Subsequently to the place of hand control steam and electricity came.
